Occasional Thoughts

I'm glad to be able to depricate my own post Groovy++-with-Maven a couple of weeks ago. The Groovy++ team has already taken action and provides the groovvypp libraries in a commonly accessible repository. They also provide a preliminary version of the gmaven plugin that supports statically linked Groovy.

For details see Using-groovypp-with-maven  and also the related update Using-groovypp-with-maven (update).

Robert Eckstein from Sun Microsystems has created a video tutorial that gives a quick, but great introduction to JavaFX.

However isn't it embarrassing that Sun is using Flash to deliver this video? Seems like Sun does not trust its own technology and rather uses the technology of a competitor. Would Microsoft ever use Flash for Silverlight tutorials? Hardly!

The Apache project in contrast seems to have more trust in the Java technology than Sun and delivers the keynote video for ApacheCon Europe as applet. And this applet proves that even Java applets can deliver Videos in just a few seconds using JDK 1.6u10.

Migrating an existing Java project for use with Hibernate is a difficult process. And yet I'm not sure if it is worth the work at all.

Some years ago I started a Java project with direct database access using JDBC and SQL. I designed my object model and a relational database schema. Both were optimized independenlty to work optimal in their environment. In order to connect the object world with the relational world, I wrote a clean storage layer, which was responsible for communicating with the database. This worked pretty good. But when Hibernate was becoming more and more popular, I started thinking about migrating to a Hibernate based object mapping.

No closures for Java 7!

This was just due to the fact that the folks are not able to agree on a solution, while Closures are a very very old concept already used in Smalltalk (Blocks) and are an essential concept for modern dynamic languages like Groovy or Ruby.

To me this is prove that either the JSR process needs a major overhaul urgently to become more flexible or the end of Java is near.

The service menus for subversion provide quick access to the most common tasks when using subversion. It is aimed to be a little bit like Tortoise SVN for that other "Operating System".
